+ | pro: | ||
+ | * fulfils all initial power supply criteria | ||
+ | * **set output is within accuracy** | ||
+ | * good design, lay out, quality components | ||
+ | * fast first contact response | ||
+ | |||
+ | contra: | ||
+ | * output is not switched of completely | ||
+ | * **measured value is up to 0.4 V lower than output voltage** | ||
+ | * second digit after . of voltage is always 0 and not settable (it should not be displayed in this case) | ||
+ | * second digit after . of voltage is always 0 and does not show measured value (the actual measured data is precise enough to show this digit) | ||
+ | * can skip fast knob turns | ||
+ | * USB cable does no fit in port because of the indent | ||
+ | * information in english programming manual missing | ||
+ | * small mistakes in programming manual | ||
+ | * can not be calibrated by end user, and vendor only calibrates if under warranty | ||
